The experiment was divided into 2 phases (Grower and Finisher) in a 16-week trial. A total of 120 [(Landrace × Yorkshire) × Duroc] growing pigs (BW; 22.02 ± 0.08 kg) were randomly assigned to control (CON) and treatment diets (TRT): CON – basal diet, DDGS 4% for growing pigs and 6% for finishing pigs; TRT1 – DDGS 10% for growing pigs and 12% for finishing pigs and TRT2 – DDGS 15% for growing and finishing pigs. Increasing dietary DDGS supplementation did not cause significant linear or quadratic responses in average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR). Furthermore, DDGS inclusion did not result in linear or quadratic effects on the digestibility of dry matter (DM), nitrogen (N), and digestible energy (E). Backfat thickness (BFT) tended to decrease (quadratic, P = 0.057) at week 16, whereas lean meat percentage (LMP) was unaffected by increasing DDGS levels in the diets. Thus, the addition of increasing DDGS levels (4–15%) to the basal diet showed no adverse effect on the growth performance, nutrient digestibility, and positively affected carcass quality of growing-finishing pigs, suggesting that DDGS (4–15%) inclusion exerted comparable effects to soybean meal, i.e. the main source of protein, thereby reducing feed cost.","PeriodicalId":14919,"journal":{"name":"Journal of Animal and Feed Sciences","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43286077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was previously demonstrated that supplementation with a mixture of xylanase and cellulase enhanced performance and nutrient digestibility in steers (Gómez-Vázquez et al., 2011) or cows (Yang et al., 2000). However, other researchers observed that average daily gain (ADG) and feed conversion ratio (FCR) were unchanged with supplementing xylanase and cellulase mixture (Krueger et al., 2008). The divergent responses should be related to the differences in activities and formulations of enzymes used in these studies. Eun et al. (2007) demonstrated that the optimum dose proportions and activities of supplied FE were critical for the magnitude of the improvement in forage utilization. The factors limiting the digestion of dietary fibre by rumen microbes were some plant cell wall ABSTRACT. The aim of the study was to evaluate the influences of fibrolytic enzymes mixture (FEM) – a mixture of cellulase, xylanase, pectinase and laccase – on nutrient digestion and ruminal fermentation in bulls. Eight Holstein bulls fitted with rumen cannula were used in a replicated 4 × 4 Latin square design and allocated to four treatment groups: control, low-FEM (LFEM), medium-FEM (MFEM) and high-FEM (HFEM) with 0, 0.25, 0.50 and 0.75 g/kg FEM, respectively. Even though the addition of FEM had a positive linear impact on dry matter (DM) intake and average daily gain, it had no influence on feed conversion ratio. Supplemented FEM linearly promoted nutrients total-tract digestibility, reaching greater values at 0.50 and 0.75 g FEM/kg DM. Rumen pH value and the ratio of acetate to propionate were reduced linearly, the concentration of total volatile fatty acids (VFA) elevated linearly but the content of ammonia-N was not influenced with increasing dose of FEM. For corn silage rumen degradation, effective degradability (ED) of DM and organic matter were quadratically reduced, reaching greater values in MFEM, whereas ED of neutral detergent fibre was linearly elevated. Supplemented FEM linearly increased activities of cellulolytic enzymes, α-amylase and protease and populations of bacteria, fungi, protozoa, Fibrobacter succinogenes, Ruminococcus albus, Prevotella ruminicola, Butyrivibrio fibrisolvens and Ruminobacter amylophilus, but had no impact on populations of methanogens and Ruminococcus flavefaciens. Supplemented FEM linearly increased urinary total purine derivative excretion. So, it was indicated that FEM enhanced nutrient digestibility and total VFA production, the optimum dose was 0.50 g/kg DM in bull diets.

Chitosan is a biodegradable, antimicrobial, antifungal polysac-charide, thus used as an additive in different industries. Effects of chitosan supplementations on silage quality traits of alfalfa were investigated in the present study. Chitosan was supplemented into alfalfa silages at four different levels: 0% – CONT group; 0.5% – CHTS0.5 group; 1% – CHTS1.0 group; and 2% – CHTS2.0 group. Neutral detergent fibre (NDF) and neutral detergent insoluble crude protein (NDICP) values increase in CHTS 2.0 group ( P < 0.05). Lactic acid and butyric acid contents decreased ( P < 0.05), acetic and propionic acid contents increased with chitosan treatments. On the day of opening the silages, mould production was not encountered, and yeast production decreased in chitosan-supplemented groups. Excessive yeast production was encountered, but mould development was not seen in chitosan-supplemented groups 5 days after opening the silages. Silage pH values increased with chitosan treatments ( P < 0.05). So, it can be concluded that chitosan negatively influenced fermen tation quality of alfalfa silage, but reduced mould and clostridial development.","PeriodicalId":14919,"journal":{"name":"Journal of Animal and Feed Sciences","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47842800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
